The Lowdown

Righto, folks, Rusty here. Let’s have a look at what’s cookin’ for Jaconé over the next couple of weeks.

The pattern starts with a bit of a slow roll, but the windows of clean, rideable swell are definitely there if you’re patient. The water temp is sitting right where it should be for this time of year, so no surprises there.

The standout session is gonna be Thursday, 3rd September in the morning at Jaconé. We’ve got a solid 8ft swell rolling in from the south, with a period of 10 seconds. That’s a nice, powerful groundswell for the reefs. The wind is a glassy light breeze from the north-northeast, keeping it completely clean. The combined energy is pumping hard at 1223 (moderate to strong energy), and the conditions are dialed for experienced surfers. It’s going to be a ripper, but with crowds *sometimes*, you might have to share the peak.

Before that, Saturday 29th August is a solid warm-up. Morning brings a clean 4ft easterly swell, with a light offshore breeze from the east-northeast. The energy is moderate at 282, and it’s a fun, clean wave. The afternoon drops a touch to 3ft, but the wind swings cross-offshore, keeping it tidy.

Monday 31st August afternoon is another little gem. The swell pushes back up to 4ft, from the east, and the wind goes nearly dead calm with a slight air. The combined energy jumps to 321, making for a clean, punchy wave.

Now, we hit a bit of a rough patch from Tuesday through to Wednesday, with strong onshore winds and messy conditions. Wednesday the 2nd sees a big, raw 10ft to 13ft south-west swell, but it’s blown out by strong winds. That’s for the kite crew, not the paddle.

After the Thursday standout, the surf settles back down. Friday 4th September morning offers a clean 4ft south-southeast swell with a light offshore breeze – a solid 327 energy – but it’s short-lived as the wind picks up in the arvo.

The second week gets a bit more interesting again. Sunday 6th September morning is a weird one: a tiny 2ft south swell, but with a very long 16-second period. That’s all class, but it’s tiny. Better for the point breaks if it wraps in.

Then, Tuesday 8th September morning is the next big standout. We’re looking at an 8ft south swell, 12-second period, with a light offshore breeze from the north-northeast. The combined energy is massive at 2129 (strong energy). That’s a serious, powerful groundswell, and it’s going to be clean. Again, this is for the experienced crew, and the crowds will be *sometimes*.

The Thursday 10th September afternoon is a special mention. The swell is 6ft from the south, 13-second period, but the wind drops to glassy. The energy is 1453, and the conditions are set to be absolutely perfect. A real treat for the patient.

The forecast closes out with a few smaller, cleaner days, but nothing else that screams “drop everything and go.” The long-range stuff is promising, but you know how it is – keep an eye on it.

Get on it, Rusty.

Information about the Jaconé Surf forecast

The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.

Jacone is 14 km (9 miles) from the city of Saquarema. If you plan a holiday in Rio de Janeiro, look for hotels and other accommodation in Saquarema. Saquarema has rooms for a wide range of budgets as well as car hire and transport links.
